Telephonic-interface lottery system

ABSTRACT

A telephonic-interface lottery system D interfaces with a multiplicity of individual terminals T 1 -Tn of a telephone network facility C to enable lottery players to call and play for at least one additional chance to possibly win by dialing a pay-to-dial telephone number indicated on a “scratch-off” or online game lottery ticket for use in the system. At the terminals, callers are prompted by voice-generated instructions to provide digital data, such as their telephone number, age, social security number, and/or drivers license number. In addition, the sequence number of the caller as well as the date and time of the call is recorded for positive association with a caller and is stored for processing. The caller&#39;s identification data is confirmed using various techniques and callers may be ranked and accounted for on the basis of entitlement-and sequence. In accordance with one format, an instant winner is selected online by utilizing techniques such as determining a random winning sequence number or a winning lottery number generated by a number generator. As an adjunct or alternative, the identification data is processed at a later time to determine a grand prize drawing winner by using various processing techniques for determining winners.

BACKGROUND AND SUMMARY OF THE INVENTION

[0002] Various forms of publicly accessible communication systems forproviding access to a central station have been proposed, some involvingtelecommunications. However, sometimes a need for ancillary functionsarise in that regard, e.g. it may be desirable to positively identify alarge group of persons, statistically analyze data from the group so asto accurately identify certain persons in the group and select a subset,or sub subsets of at least one person. In that regard, a need exists foran improved, effective, economical, and expedient system oftelecommunication incorporating means for performing qualification,identification, analysis and selection of individual persons.

[0003] It has been proposed to interface persons at telephone callingstations directly with a computer facility. In accordance with sucharrangements, recorded voice messages prompt callers to provide data byactuating the alphanumeric buttons that are conventionally employed fordialing from one telephone station to another. In one prior arrangement,a caller may actuate dialing buttons to selectively attain acommunication channel or to address specific information in a computer.In another arrangement, dialing buttons may be actuated to specify anindividual billing designation as for requested services. Generally,such systems are believed to have been somewhat limited in scope, ofteninvolving difficulties that are frustrating or confusing to a caller.Nevertheless, such techniques have been widely used to enhance andbroaden communication.

[0004] The public lottery has become widely accepted as a basis forsupporting government activities while providing aspects ofentertainment and hope. Typically, conventional public lotteries havebeen facilitated by computers and data processing systems utilizingvarious formats. One conventional type of lottery incorporates the useof “scratch-off” lottery tickets that are sold by retailers. Under thissystem, winning tickets are returned to lottery retailers who redeem thetickets for the prize amounts, based on a physical approval of thelottery ticket.

[0005] In general, the present invention comprises atelephonic-interface lottery system and related process to furtherstimulate interest in the lottery by providing at least one additionalchance to possibly win some prize (whether or not the scratch-offlottery ticket is a winner) by calling a pay-to-call number indicated onthe scratch-off lottery ticket. The telephonic-interface lottery systemcan also be utilized with online tickets in which case the onlineterminal printer can print at least one unique identification number(either the existing printed ticket or lotto number or a new specialnumber which may be interrelated to the existing ticket number) forsubsequent telephone use. In one embodiment, scratch-off lottery ticketsfor use in the telephonic-interface lottery system include primaryindicia defining a lottery format to evidence a winning lotterycombination and at least one unique identification number used to pursuethe additional chances. The lottery format and at least a portion of theidentification number are concealed. The telephone number facilitating aplay of the additional chance is a pay-to-call number, such aspreferably a 900 phone number.

[0006] The telephonic-interface lottery system utilizes both analog(voice) and digital telephonic communication in a variety of differentinterface formats or programs, to record data relating to each caller,in particular data formulated by the lottery system such as the sequencenumber of the call including the date and time at which the calloccurred, data provided by the caller such as the area code andtelephone number followed by the unique identification number oradditional chance number from the lottery ticket. The system isconfigured to eliminate duplicate entries and verify the uniqueidentification number. Instant winners can be selected while the lotteryplayer is on the telephone by a designated winning sequence number or bya random number generator. In addition, winners can also be selected ata later designated time by a designated winning sequence number or bythe random number generator.

DESCRIPTION OF THE ILLUSTRATIVE EMBODIMENTS

[0018] As required, detailed illustrative embodiments of the presentinvention are disclosed herein. However, physical communication systems,data formats, and operating structures in accordance with the presentinvention may be embodied in a wide variety of forms, some of which maybe quite different from those of the disclosed embodiments.Consequently, the specific structural and functional details disclosedherein are merely representative; yet in that regard, they are deemed toafford the best embodiments for purposes of disclosure and to provide abasis for the claims herein which define the scope of the presentinvention.

[0019] Referring initially to FIG. 1, a series of remotetelephone-instrument terminals T1 through Tn are represented (left). Theterminals are generally similar, and accordingly, only the terminal T1is illustrated in detail.

[0020] In the disclosed embodiment, the remote terminals T1 through Tnrepresent the multitude of conventional telephone terminals that arecoupled to a communication facility C which may take the form of acomprehensive public telephone system for interconnecting any associatedterminals T1-Tn. In accordance with the present system, the terminalsT1-Tn operate through the communication facility C to be coupled with acentral station D, an embodiment of which is illustrated in some detail.

[0021] Generally in accordance with the present development, individualcallers use the individual telephone stations T1 through Tn to interfacethe station D through the communication facility C. Callers may bescreened or qualified. Also in accordance herewith, the data ofindividual callers including digital data provided by callers may becollected, correlated and tested in the station D for processing inaccordance with various programs and external data. As a consequence,various objectives are accomplished. For example, a select subset of thecallers may be isolated and specifically identified, or related data maybe processed, or transactions may be actuated. The possibilities forapplication of the system are substantial and varied as will be apparentfrom the exemplary structure and functions as described in detail below.

[0022] In one operating process format, legal lotteries are enabled thatare interesting, effective and very economical on an individualparticipant basis. The telephonic-interface lottery system of thepresent invention further stimulates interest in the lottery byproviding at least one additional chance to possibly win a prize inaddition to a winning lottery format provided on a scratch-off lotteryticket or an online ticket. The additional chance is facilitated bycalling a pay-to-call number indicated on the scratch-off lotteryticket. Some formats may use toll free 800 numbers as well.

[0023] The callers may be variously qualified on the basis ofentitlement and may be identified for subsequent verification. Thecallers may be prompted, either through the interface or externally, toprovide appropriate data, such as their age and the additional chancenumber which may be one or more unique identification numbers.

[0024] Considering the system of FIG. 1 in somewhat greater detail, itis to be understood that the communication facility C has multiplexingcapability for individually coupling the terminals T1-Tn to the centralstation D on request. In the illustrative embodiment of the system, thecommunication facility C comprises a public telephone network and theindividual terminals T1-Tn take the various forms of existingtraditional or conventional telephone instruments.

[0025] The exemplary telephone terminal T1 is represented in some detailto include a hand piece 10 (microphone and earphone) and a panel 12provided with a rectangular array of push buttons 14 in the conventionalconfiguration. Of course, the hand piece 10 accommodates analog signalswhile the panel 12 is a digital apparatus. Generally in accordanceherewith, the hand piece 10 serves to manifest analog signals vocally tothe caller.

[0026] In accordance with conventional telephone practice, alphabeticand numeric designations are provided on the buttons 14. For example,several of the buttons 14 carry three letters along with a decimaldigit. Specifically, the button designated with the numeral “2” alsocarries the letters “A”, “B” and “C”. In that manner, the buttons 14encompass the numerals “0-9”, two symbols, and the alphabet except forthe letters “Q” and “Z”. Consequently, the buttons 14 accommodate theentry of decimal data, and to some extent alphabetic data.

[0027] The buttons 14 designated with symbols “*” and “#”, along withthe numeral “0”, can be used by predetermined assignment to representthe letters “Q” and “Z” or any of a variety of other data or commandcomponents. Generally, in accordance herewith, the buttons 14 areemployed to formulate digital data at the central station D in variousformats determined by the instant specific use and operating format ofthe system.

[0028] Considering the central station D in somewhat greater detail, thecommunication facility C is coupled to interface a series of processingsystems P1 through Pn (FIG. 1, right). Specifically, the communicationfacility C is connected to the processing systems P1-Pn through anassociated series of automatic call distributors AC1 through ACn. Eachof the automatic call distributors AC1-ACn accommodates one hundredlines from the communication facility C and accordingly, may accommodateand queue up to 100 calls.

[0029] Each of the automatic call distributors AC1-ACn may take variousforms as well know in the prior art, functioning to queue incoming callsfor connection to a lesser number of lines. Also, in various systemsaudio response units (ARU's) may be used as for preliminary processingin accordance with the operations as described below.

[0030] In the disclosed embodiment, from each of the call distributorsAC1-ACn, fifty lines are connected respectively to the individual dataprocessing systems P1-Pn through an interface 20 and a switch 21. Thus,in the disclosed embodiment, each of the automatic call distributorsAC1-ACn can accommodate one hundred lines, fifty of which may be activein association with one of the processing systems P.

[0031] The processing systems P1-Pn are similar, therefore, only theprocessing system P1 is shown in any detail. Collectively, theprocessing systems P1-Pn are interconnected with a command computerterminal CT, at least one interface terminal IT, at least one printer PRand an audio unit AD. The command terminal CT is separately coupled tothe audio unit AD.

[0032] As represented, the processing systems P1 through Pn each containa number of individual function units or processors PR1 through PRn.Although various other configurations and arrangements may be employed,the explanation is facilitated by including a plurality of individualfunction units as treated in detail below.

[0033] Considering the processing system P1, fifty lines from theautomatic call distributor AC1 are connected to the interface 20, anexemplary form of which may be a commercially available Centrum 9000unit. The interface 20 incorporates modems, tone decoders, switchingmechanisms, DNIS and ANI capability (call data analyzer 20 a) along withvoice interface capability. Note that the interface may actually performanalysis on data. However, to preserve the disclosed embodimentmanageable, major analysis is explained with reference to processors.

[0034] Generally, DNIS capability is a function of the communicationfacility C (composite telephone system) to provide called terminaldigital data indicating the called number. ANI capability is a similarfunction whereby the digital data indicates the calling number withcalling terminal digital signals. Both capabilities are available foruse with equipment as the interface 20 and to provide control throughthe call data analyzer 20 a.

[0035] Accommodating up to fifty independent calls on separatecommunication paths to the central station D, the interface 20 iscapable of providing analog (voice) signals to prompt each caller. Alsoaccommodated are digital signals including the DNIS and ANI signals. Thesystem contemplates the possibility of utilizing sequences of lines inrotary as well as blocking sequences of lines, the numbers for whichcommand a particular program or operation format of a function unit asdisclosed in detail below.

[0036] The interface 20 provides the connection of the fifty lines to aswitch 21 which is in turn coupled to fifty function units, orprocessors PR1-PRn. As indicated above, multiple function units, orprocessors, are described in the disclosed embodiment to facilitate theexplanation. Of course, non-parallel techniques and multiplexedoperations might well be employed as alternatives. For a similar reason,as disclosed herein, each of the processors PR1-PRn includes memorycells for each of the callers' individual data. Development andcompilation of data in such cells according to various operating formatsis described below. In the disclosed embodiment, the processors PR1-PRnare connected collectively to the command computer terminal CT(incorporating a CRT display), the interface terminal IT, and theprinter PR. Note that the CRT display serves to visually display dataregarding select subsets as explained in detail below.

[0037] Exemplary detailed structures for the processors PR1-PRn aredescribed below; however, in general, the units may comprise amicrocomputer, for example, programmed as suggested above and asdisclosed in detail below to accomplish specific operating formats. Asan integral part of such formats, a caller may be qualified as belongingto an entitled set of persons, such as persons holding a proper lotteryticket and being over a certain age. Also, callers may be designatedboth with respect to their significance and their identification. Forexample, callers may have different significance in a format, dependingon the time or sequence of their call. Also, the designation of a callermay be exceedingly important in relation to the caller eventually beingisolated as part of a subset or sub subsets, the members of whom must beaccurately verified.

[0038] As described below, in a lottery format the designations mayinvolve multiple elements which may include: random number assignments,encryption techniques, utilization of calling numbers, identificationdata, sequence of call and so on to facilitate reliable verification.Note that the communication facility C has a customer billing structureB that is interfaced by the system.

[0039] On the qualification and designation of callers, the systementers a data receiving phase during which digital data (formatted atone of the telephone terminals T1-Tn by the caller) is processed by oneof the processors PR1-PRn. In general, the processing evolves a subset(at least one caller) and also possibly a sub subset, the members ofwhich may be verified and confirmed.

[0040] Either during the data accumulation phase, or after theprocessing phase to isolate a subset, a distinct operation may involveactuating the interface terminal T1 for direct communication between thecaller and an operator at the terminal T1. Another distinct operationmay involve actuation of the printer PR to provide documents in relationto the operating format, as for providing award certificates as forverifying members of an isolated subset. Also, charge slips may begenerated containing at least part of the data of a particulartransaction.

[0041] A general sequence of operations for a format is represented tobe initiated in FIG. 3 by the “enter” block 40 which is accordinglyfollowed by a “cue voice generator” command block 42. If the ANI(automatic number identification) equipment is not employed, the voicegenerator in the interface 20 formulates speech, a representative formof which might be: “Thank you for participating in the lottery. Pleasegive us your telephone number by actuating the call buttons on yourtelephone instrument.”

[0042] Acting on the instructions, the caller would push the buttons 14in sequence to indicate his telephone number, e.g. “(213) 627-2222”.Alternatively, the interface 20 can accept the calling number ((213)627-2222) according to its provision by standard ANI equipment of thecommunication facility C.

[0043] The resulting data signals are communicated from the interfaceunit 20 (FIG. 1) to the processor PR1 for testing the telephone numberas valid or entitled. Essentially, the format of a proper number promptsproduction of a valid or “good” signal. The test is indicated by theblock 44 (FIG. 3). If the response is not valid or entitled, for examplecontains an inappropriate number of digits or has been used to a pointof excess, the operation of block 46 is initiated again cuing the voicegenerator 30 (FIG. 1). The voice generator accordingly instructs thecaller, e.g.: “You have not entered a proper telephone number. Pleasereenter your telephone number by pressing the appropriate call buttons.”The caller is then allotted a predetermined period of time to make aproper entry with the consequence that the system moves to a testoperation as indicated by the block 48 (FIG. 3). Specifically, block 48poses the query: “Is the second try good?”

[0044] If the caller is again unsuccessful, the system purges the recordas indicated by the block 50 and the call is terminated as indicated bythe block 52. In an alternative mode, the processor PR1 may abort theinterface and couple the interface terminal IT for direct personalcommunication with the caller. The interchange would then proceed,person-to-person.

[0045] If the caller responds with a proper telephone number, theoperation proceeds. Specifically, the system sequences to record theresponse of the proper telephone number as indicated by the block 45.That is, the caller's telephone number is recorded in an assignedspecific memory cell identified with the caller. The format of the cellC1 is indicated in FIG. 7 showing the individual fields or sections. Thefirst portion, section 53, contains a form of identification data, i.e.,the caller's telephone number, i.e. “(213) 627-2222”.

[0046] Note that as explained above, if the second attempt to formulatea proper number is successful, as manifest by the block 48 (FIG. 3), theresponse is recorded at that stage. In either case, exiting from theblock 45 (FIG. 3) invokes the next operation of again queuing the voicegenerator as indicated by the block 56.

[0047] At this juncture, the system proceeds to receive and process thelottery ticket data as well as other data such as the identificationdata provided by the caller and the data formulated by the computer. Theresult is a subset of winners, or perhaps ultimately several subsets orsub subsets of winners or potential winners. However, first the lotteryticket number (such as the unique identification number) is entered bythe caller as indicated by the block 68. The lottery number may bestored in section 66 (FIG. 7) of cell C1.

[0048] At the outset, the system may test the lottery ticket number onthe basis of its format. That is the number is verifiable (as by digitcombinations, for example the first two digits may equal the third) andis tested as explained above in relation to the telephone number. If areceived number is invalid, the call may be terminated as explainedabove. Any record may be purged.

[0049] If the number is valid, it is next tested as a winner.Essentially, the number is treated as a consumable key, entitled forexample to a single use for participation. The participation may includean online subset determination of winners and a subsequent offlinedetermination of another subset of winners. These tests are indicated bythe block 68. From that point, as illustrated by the block 70, data isaccumulated for subsequent offline processing.

[0050] The detailed operation is not represented in FIG. 3 as it issimilar to the operation illustrated by the blocks 42 through 56.However, again, a proper response is registered in the storage cell C1as illustrated in FIG. 7 by the number “58”.

[0051] During the course of the telephonic communication, the processorPR1 formulates identification data for the caller specifically such as:the date and time of the call, the chronological sequence of the call,the assigned designation of the call, and a set of acknowledgment digitsfor the call. Such data identification is registered in the caller'sassigned cell C1 in accordance with the format of FIG. 2 being stored insections 62, 64, 67 and 69. Note that the data may be stored in a codedinterrelationship. For example, the acknowledgment digits may be relatedto the call record sequence. In the illustrative example, thechronological order number of the caller is 4951. The acknowledge digitsmay be derived from the sequence number. For example, as illustrated, acoded relationship may be established by adding “two” to each of theindividual record sequence digits. Considering the example numerically:

[0052] Adding without propagated carries: $\frac{\begin{matrix}4951 \\2222\end{matrix}}{6173}$

[0053] Note that the confirmation data as acknowledgement digits can beextremely important, as to communicate with an isolated member of asubset. For example, identification of an ultimate winner could bepublished or circulated, as by a television broadcast, then respondentschecked by use of confirmation data that may be confidential.

[0054] Continuing with the above example, the call chronologicalsequence registered for the caller is 4951 as represented in the section62 while the acknowledge digits are 6173 as registered in the section66. Additionally, the processor PR1 develops an assigned designationnumber, e.g. designation “4951684”, which is registered in the section67, the acknowledge code or digits, e.g. 6173, being registered in thesection 69. These values are formulated in accordance with conventionalnumber techniques during the data acquisition phase. With the exemplarynumerals formulated, the operation proceeds.

[0055] In the detailed operation, in addition to entering data from theremote terminal, the processor PR1 (FIG. 1) cues the internal memory asindicated by the block 70 (FIG. 3). Thus, the processor PR1 fetches thecall record sequence number, assigns a designation (if not previouslyassigned, in some cases the sequence number is the designated number),and encodes the sequence number as the acknowledgment digits (if notpreviously accomplished).

[0056] To confirm receipt of the acknowledgement digits, the processorPR1 (FIG. 1) cues the voice generator in the interface 20, as indicatedby the block 72 (FIG. 3) to provide information to the caller.Specifically, for example, the voice generator in the interface 20(FIG. 1) might signal: “This transaction has been designated by thenumber 4951684, and is further identified by the acknowledgment digits6173. Please make a record of these numbers as they will be repeated.Specifically, the designation number is 4951684. The acknowledgmentdigits are 6173. Please acknowledge this transaction by pressing yourtelephone buttons to indicate the acknowledge digits 6173.” In lotteryapplications typically involving security, the order and acknowledgmentof callers may be very important. Therefore, data for confirmationassociated with the order is important.

[0057] The system next proceeds to the test mode as indicated by theblock 76 (FIG. 3). If the caller provides the correct acknowledgmentdigits, the data is confirmed in the record as indicated by the block 80and is registered in the cell C1 (FIG. 2). Additionally, the voicegenerator is sequenced as indicated by the block 82 (FIG. 3) to indicatethe close of the communication and that the transaction is terminated asrepresented by the exit block 84.

[0058] In the event that a caller cannot confirm his acknowledgmentdigits, as indicated by the block 76, a repeat operation is performed asindicated respectively by the blocks 86 and 88. Specifically, the voicegenerator is queued for a second instructional message. In the eventthat the second attempt also fails, the data is purged and the calldiscounted as indicated by block 90 and an exit block 92. If the secondtry is successful (test block 88), as indicated by the block 80, therecord is perfected as indicated above.

[0059] As a result of the likelihood of a large number of calls, asdescribed above, data cells in the processors PR1-PRn (FIG. 1) aredeveloped with specific information relating to each call. Such data,accumulated from the various calls may be considered by logiccomparisons in the computer 22 to select the subset of winning personswho should be isolated at a later point.

[0060] The processing operation usually involves comparison testingwhich compares caller data from individual memory cells of theprocessors P1-Pn (FIG. 1) with test data, such as a look-up table, thatis supplied through the command terminal CT.

[0061] Preliminary to considering an exemplary form of thetelephonic-interface lottery system of the present invention, referencewill now be made to FIG. 4 showing an exemplary structural form for theprocessors PR1-PRn. From the switch 21 (FIG. 1) a pair of communicationlines 90 and 91 are indicated in FIG. 4 (top left). The line 90 providessignals from a processing unit 92 while the line 91 provides signals tothe processing unit 92 along with other components as represented inFIG. 4. The separate lines 90 and 92 facilitate explanation.

[0062] The processing unit 92 may take the form of a mini-computerprogrammed to accommodate the functions of various applications, asdisclosed in detail below. As indicated above, the system may utilize aplurality of independent function units or processing units, e.g.,processing unit 92, operating in a somewhat parallel configuration, oralternatively, a limited number of processors may be driven sequentiallyto accommodate the functional operations as described.

[0063] The input line 91 (upper left) is connected specifically to aqualification unit 93, a sequencer 94 and a designation unit 96, as wellas the processing unit 92 as indicated above. The qualification unitqualifies access from a remote terminal T1-Tn to the processing unit 92as described in detail below. In accordance with various applications oroperating formats, the qualification unit 93, the sequencer 94 and thedesignation unit 96 operate preliminarily with respect to individualcallers. Generally, these units qualify or test callers for entitlementto participate in the lottery, develop a sequence-of-calls record andprovide forms of designations for callers that may be authenticated. Asdescribed in detail below, the units function in sequence to accomplishsuch operations and accordingly are each individually connected to theprocessing unit 92 and a buffer storage 97. Essentially, the bufferstorage-97 is illustrated separately from the processing unit 92 alongwith the unit 93, sequencer 94, unit 96, and so on, again in order tofacilitate the explanation. Similarly illustrated are a memory 98 (withcells C1-Cn), a look-up table 103 and a clock 105.

[0064] Considering the processor of FIG. 4 in further detail, thequalification unit 93 (upper left) is connected to a look-up table 99and a use-rate calculator 100. The designation unit 96 (top center) isconnected to a random number generator 101 and an encryptor 102.

[0065] In view of the above structural description of the system,consideration will now be given to a certain specific application inrelation to the operation of the system.

[0066] As the illustrative operating format, an embodiment of thetelephonic-interface lottery system will now be described. The legalizedstate lottery typically features various “scratch-off” ticket lotterygame formats such as “the California Classic”, “Treasure Hunt”,“Blackjack”, “Lucky 7's” and the like. In addition, lotteries typicallyoffer online games such as Lotto. The enhanced lottery systemaccommodated by the present telephone system may utilize pay-to-dialnumbers (“900-xxxx”) or toll free 800 numbers and may be restricted to alimited number of uses for defined intervals of time. For example, aperson might be entitled to play the lottery only a limited number oftimes or to the extent of a limited dollar value during a predeterminedinterval.

[0067] Certain digits of the unique identification number may containinformation on a particular format, for example the “CaliforniaClassic”. Multiple formats may run simultaneously and the DNIS forexample may indicate the lottery format and processing for each game.Additionally digits in the unique number when entered by the callermight indicate a telephone subformat.

[0068] Referring now to FIG. 2, a lottery participant upon purchasing a“scratch-off” lottery ticket LT for use in the system D has at least twochances to win. The first chance is facilitated by a lottery formatdefining a winning combination, for example by matching three likedollar amounts or symbols from a plurality provided in a first sectionSl. Subsequent chances are provided by telephone communication inaccordance herewith. Preliminarily, consider the specific structure of aticket in accordance herewith.

[0069] The lottery ticket LT is made from any suitable base substratetypically used and is likewise suitably sized to accommodate all theinformation. A scratch-off layer covers part or all of the ticket.Structurally, the ticket LT is a composite including a base substrate L1(FIG. 2a) bearing a latex scratch-off layer L2. Visible print or indiciaL3 appears on the latex layer L2 which may be integral or over stamped.Concealed indicia L4 is fixed on the substrate L1 and is revealed whenthe latex layer is removed. As illustrated in FIG. 2, the concealingareas S1 and S2 of the latex layer L2 are illustrated by wavy lines,accordingly normally concealed indicia is revealed.

[0070] As illustrated in FIG. 2, the upper section S1 of the scratch-offlatex layer L2 defines ticket-specified winners. That is, as indicatedabove, matching combinations or symbols define winners. The lowerscratch-off section S2 of the ticket LT indicates a uniqueidentification number UN which may be several digits. The first sectionS1 and at least a portion of the identification number UN is coveredwith a suitable substance, such as latex in order to conceal the lotteryformat and the complete identification number from the lotteryparticipants, retailers and the like and prevent any fraudulentactivity. The unique-identification number may also be the stock number(sequence number assigned by the lottery for each ticket to keep trackthereof) of the lottery ticket with additional concealed or latexprotected digits.

[0071] The lottery ticket LT also indicates the pay-to-dial telephonenumber indicia 59 to facilitate additional chances to win. For example,the lottery ticket LT bears indicia 61 indicating “For Another Chancecall 900-555-1212”. Accordingly, regardless of whether the lotteryticket LT defines a winning combination, the lottery participant hasanother chance to possibly win by dialing the pay-to-dial number andincurring a further minimal cost, for example 50 cents. In some formatsall players including winners of the matching combinations are providedwith an additional opportunity to win. Note that the ticket LT alsocarries another number as indicated by the unconcealed indicia 63.

[0072] The lottery ticket LT on its reverse side is provided with a barcode BC defining a number corresponding to the unique identificationnumber UN which would allow the retailer or the lottery system to verifyinstant winners when the lottery tickets are redeemed and automaticallycancel related information on the data stored in the memory.

[0073] Pursuing the operation of the system in greater detail, using thespecified calling number (900 555 1212) from the terminal T1 (FIG. 1)the caller would actuate the push buttons 14 to establish contact withthe processing system P1. Communication would be through thecommunication facility C, the automatic call distributor AC1, theinterface 20 and the switch 21 as described in detail above.

[0074] The initial operation involves qualification of the caller toparticipate in the lottery. Again, ANI or caller interface techniquesmay be employed as described above. If the caller is involved, theinterface 20 is actuated by the qualification unit 93 during theoperating interval t1 to instruct the caller: “Please key in yourtelephone calling number”. As indicated above, an alternative involvesthe system simply registering the calling number on the basis of itsprovision by ANI equipment. As indicated above, in one sequence thecallers telephone number is tested at this point. Also, the lotterynumber also may be tested at this stage or subsequently. Varioussequences are practical, another of which involves data accumulationprior to winner tests.

[0075] After the caller's telephone number is registered, theinstruction is given: “Participation in the lottery is for persons overtwenty-one years of age. Accordingly, please key in the year of yourbirth”. A birth date, social security number, driver's license or creditcard number may be similarly registered to confirm age or confirmidentification of caller. Alternatively, the combination of telephonenumber and date or year of birth or age could be used. In any event, thecaller's data is registered and the qualification unit 93 then functionsto test the data as provided. Specifically, the caller's telephonenumber is checked in a look-up table 99 to determine whether or not itis a proper and currently valid number for use in the lottery.

[0076] If the data indicates a qualified caller, the system proceeds tothe next phase of designating the transaction. The designation unit 96operates during the interval t3 to provide the caller with a designationfor the current transaction which may be the sequence number. Asexplained above, the random generator 101 with or without the encryptor102 may be employed to create an identification number which may includean encrypted form of the caller's telephone number. Accordingly, datafor the transaction is established in the buffer 97 then set in a cellof the memory 98 (FIG. 4). Specifically, the completed data cell formatmight be as follows: Telephone No.—Birth Year—Designation—Random No. Inthe format being described, the system next functions to generate therandom number as indicated above which will then be tested against aseries of other numbers to determine whether or not the caller is awinner. In that regard, elements in the processing unit 92 whichaccomplish the operation are illustrated in FIG. 6 which will now beconsidered in detail.

[0077] Typically, a caller will have scratched off the latex layer L2over the section S2 prior to placing a call to the lottery interfacesystem. Depending on the operating sequence employed, at some point, thecaller is cued to input the number carried by the indicia UN.Specifically, the number is simply entered using the terminal touch tonekeypad. As a result winners can be selected with online processing whilethe caller is on the phone as well as by off-line processing at a laterdesignated time. Both online and off-line winners can be selected bydetermining a winning sequence number or by selecting a random lotterynumber or selecting a random sequence number.

[0078] A random number generator 160 functions on command to provide athree-digit number. With the consummation of a call, the random numbergenerator 160 is actuated to provide the caller's random number in aselected caller cell 162. From that location, the caller's random numberis compared with numbers from a register 164 by a comparator 166. Thenumbers in the register 164 were previously passed through a gate 174from the generator 160. In the event of coincidence, the comparatorprovides an output “yes” signal to a line 168. Conversely, the failureof coincidence prompts the comparator 166 to provide a “no” output to aline 170. Essentially, a “yes” indicates a win while a “no” indicatesthe caller has lost.

[0079] The elements of FIG. 6 provide a random operating format todetermine winners on a somewhat statistical basis; however, the systemincreases the probability with the passage of time when no win occurs.In that regard, at the outset of an operating cycle, the random numbergenerator 160 provides a random number that is passed through the gate174 to the register 164. In the exemplary format, a three-digit numberwould be provided. At that stage, the caller's random number, from thecell 162, would be compared with the single number in the register 164by the comparator 166. However, with the passage of time, calls aretallied or time is metered by a counter 178. Accordingly, upon theattainment of a predetermined count, the gate 174 is again qualified toenter another number in the register 164. Accordingly, an increasing setof numbers are held in the register 164 for comparison with eachcaller's number. Of course, the more numbers in the register 164, thehigher probability of a caller winning and that relationship dependsupon the duration or number of calls since the last winner.

[0080] Either a win or a loss as indicated within the processing unit 92(FIG. 4) prompts the interface 20 to respond appropriately to the callerannouncing his results. If there is a win, the designation may bereinforced and additional identification may be taken as explainedabove. Of course, if the prize simply involves a credit on the caller'stelephone bill or his credit account, identification and designationbecome less critical considerations.

[0081] In the event of awards to be claimed, the processing system P1(FIG. 1) may actuate the printer PR to produce a positive identificationof the winner, which document may be redeemed only by the callerproviding the assigned designation along with confirmation of hisidentification data.

[0082] Generally in relation to awards, the processing unit 92 may alsoutilize a random number format for determining the significance ofawards. That is, a random number may be actuated to provide numeralsfrom one through twenty, for example, the magnitude of the numbergenerated for a caller indicating the significance of his award.Normally such information would be provided to the caller and registeredin his memory cell.

[0083] With respect to memory cells generally, it is to be noted thatactuated memory cells may be cleared for callers who are not winners.Accordingly, a limited number of memory cells store the subset ofwinners for subsequent confirmation processing and so on. Alternatively,historical data cells for each caller may be maintained.

[0084] As explained above, clearances may be perfected through thelook-up table 99 (FIG. 4) in association with the qualification unit 93or approvals through a consumable key step may be extended toincorporate functions of the processing unit 92 in association with thememory 98. For example, if qualification simply involves a check-offoperation, the look-up table 99 will normally be employed.

[0085] As explained above, the arrangement of the function unit (orunits) may be variously embodied in a single processor or manyprocessors, depending on various considerations as time sharing,multiplexing, paralleling and so on. The systems as described aboveembody the components bulked together in one location. However,components of the system could be spaced apart geographically, usingdedicated lines or polling techniques. An illustrative embodiment isshown in FIG. 9.

[0086] Call distributors CD1-CDn are located at different geographiclocations along with associated interface units IA1-IAn and IB1-IBn.Each of the interface units, as unit IA1 is coupled to an interfacecentral processing unit 260 as indicated by lines 252, 254, 256 and 258.The interface CPU 260 may be located geographically proximate theinterface units, for example in Omaha, to record and store the datarelating to each caller, including the data provided by the caller andthe data formulated by the computer in a data file 264 coupled theretoas indicated at line 266. Each of the lines may take the form of adedicated telephone line or a polling telephonic coupling. The interfacecentral processing unit 260 is coupled to a lottery central processingunit 251 indicated at line 262 which may be located remote from theinterface central processing unit 260 as for example in Indianapolis.

[0087] In the operation of the system of FIG. 9, the call distributorsCD are coupled to a telephonic communication system and accordinglyallow the interface units I and the interface CPU 260 to provideinterface communication between the lottery central processing unit 251and a multitude of remote terminals T1-Tn. The interface centralprocessing unit 260 stores complete data with regard to each caller inthe data file 264. The interface central processing unit 260 mayvariously transmit or download important data only, for example theunique identification or ticket number and prize type (such as B) orprize amount ($50) stored in section 65 (FIG. 7) to the lottery centralprocessing unit 251. Accumulated data with regard to a plurality ofcallers may be transmitted at a designated time to save on transmissiontime and cost. Downloaded data for the additional chances is also storedat a file 270. Thus, the distributed-component system is capable ofexecuting the various formats as explained above with reference to theillustrative structure.

[0088] In view of the above explanation of exemplary systems, it will beappreciated that other embodiments of the present invention may beemployed in many applications to accumulate statistical data, processsuch data, and define subsets of callers of concern.
